I am trying to figure out a way to control DC powered lights in my RV. All I want is to have some sort of hardware relay that will allow me to set bindings to turn them on and off. That’s really it. I’ll get more complicated later, but I’m just starting out with this, so if I can get some lights to work, I know I’ll have the first step built.
Does anyone know of a relay I can buy or build that would receive a signal from a raspberry pi running openHABian? I looked at Z-Wave and the Fibaro RGBW controller, but that has color control and dimming and costs nearly $70. I want to start with something more simple and less expensive. Is there something out there that would work in this situation? If its wifi, that’s great. If I have to buy a Pi Zero and make it somehow connect, I can do that. I’m just not sure how to do it right now and looking for ideas and insight.
